The diagram shows a waveform from a simple class-C circuit without the tuned load.

In the film, Dr. Cid attempts to create a " waveform " from the positive energy signature of the Earth's spirit, in order to combat the films antagonists, the negative energy " Phantoms ", through use of phase inversion canceling.

This is done in a similar fashion to a musician modulating a tone ( a periodic waveform ) from a musical instrument by varying its volume, timing and pitch.

( The illustration on the right ignores the effect of diffraction, which would make the waveform continuous function | continuous away from material interfaces and would add increasing distortions with distance.

The square wave is derived from the sawtooth waveform using a simple, single-transistor waveshaping circuit.

This produces a sound that is subtly different from the square waveform created by the dedicated hardware found in most analog synthesizers.

Transducer s convert signals from other physical waveform s to electrical Electric current | current or voltage waveforms, which then are processed, transmitted as electromagnetic wave s, received and converted by another transducer to final form.

In inverse filtering, the speech sound ( the radiated acoustic pressure waveform, as obtained from a microphone ) or the oral airflow waveform from a circumferentially vented ( CV ) mask is recorded outside the mouth and then filtered by a mathematical method to remove the effects of the vocal tract.

The output signal waveform can be calculated from the closed-loop transfer function and the input signal waveform.

Practically, this means that the waveform at the input will be different from the waveform at the output of the link.

Non-linear loads change the shape of the current waveform from a sine wave to some other form.

# Harmonic distortion: defined as a departure from the ideal sinusoidal waveform expected on the line.

This is a mathematical operation that effectively rebuilds a continuous waveform from its samples and then samples that waveform again at a different rate.

Aliasing matters when one attempts to reconstruct the original waveform from its samples.

However unlike additive synthesis where each harmonic is generated and added together during the actual synthesis, in wavetable synthesis, the waveform is precomputed from the harmonics and stored as wavetables that are later used during synthesis.

The function of this capacitor, known as a reservoir capacitor ( or smoothing capacitor ) is to lessen the variation in ( or ' smooth ') the rectified AC output voltage waveform from the bridge.

This mechanical movement exactly resembles the waveform of the electronic signal supplied from the amplifier's output to the voice coil.

Some switch-mode power supplies use filters or additional switching stages in the incoming rectifier circuit to improve the waveform of the current taken from the AC line.

The quality of output waveform that is needed from an inverter depends on the characteristics of the connected load.

It is capable of real-time waveform stretching, spectral modulation, and wavetable sweeping.

Due to features like PWM waveform synchronization with the ADC unit, the C2000 line is well suited to many real-time control applications.

In radio communication, a continuous wave radio-frequency signal ( a sinusoidal carrier wave ) has its amplitude modulated by an audio waveform before transmission.

The audio waveform modifies the amplitude of the carrier wave and determines the envelope of the waveform.

When processing signals, such as audio, radio waves, light waves, seismic waves, and even images, Fourier analysis can isolate individual components of a compound waveform, concentrating them for easier detection and / or removal.

The component waveform ratios are mixed by sliding drawbars mounted above the two keyboards, which operate like the faders on an audio mixing board.

Modulation of a sine waveform is used to transform a baseband message signal into a passband signal, for example low-frequency audio signal into a radio-frequency signal ( RF signal ).

If the oscillator operates above the audio frequency range (> 20 kHz ), the generator will often include some sort of modulation function such as amplitude modulation ( AM ), frequency modulation ( FM ), or phase modulation ( PM ) as well as a second oscillator that provides an audio frequency modulation waveform.

* WAV, an audio waveform file format

A typical example of linear equipment is a high fidelity audio amplifier, which must amplify a signal without changing its waveform.

An illustration of quantization of a sampled audio waveform using 4 bits.

Since the instantaneous power of an AC waveform varies over time, AC power, which includes audio power, is typically measured as an average over time.

* Dynamic range compression, also called audio level compression, in which the dynamic range, the difference between loud and quiet, of an audio waveform is reduced

** Frequency modulation synthesis, a form of audio synthesis where the timbre of a simple waveform is changed by frequency modulating it with a modulating frequency that is also in the audio range

Modern waveform monitors contain many additional modes of operation, including picture mode ( where the video picture is simply presented on the screen, much like a television ), various modes optimized for color gamut checking, support for the audio portion of a television program ( either embedded with the video, or on separate inputs ), eye pattern and jitter displays for measuring the physical layer parameters of serial-digital television formats, modes for examining the serial digital protocol layer, and support for ancillary data and television-related metadata such as timecode, closed captions and the v-chip rating systems.

Adobe Audition ( formerly Cool Edit Pro ) is a digital audio workstation from Adobe Systems featuring both a multitrack, non-destructive mix / edit environment and a destructive-approach waveform editing view.

After zooming in on the individual samples in the audio waveform, the pen tool can be used to edit the wave directly.

Files which are generated by Final Cut Pro, i. e. audio waveform display, filter effects, etc.

Many of Mathew's implementations ( such as using pre-calculated arrays for waveform and envelope storage, the use of a scheduler that runs in musical time rather than at audio rate ) are the norm for most hardware and software synthesis and audio DSP systems today.

The oscillator generates an audio waveform, which ( except for noise waveforms ) includes a fundamental pitch and a series of harmonic partials.

A base frequency was then modulated with analog filters to create desired effects ; this process of audio waveform synthesis using frequency modulation is usually referred to as FM synthesis.

For detection, the electrical field of the terahertz pulse is sampled and digitized, conceptually similar to the way an audio card transforms electrical voltage levels in an audio signal into numbers that describe the audio waveform.
